E-cigarette explodes in California teen's pocket

An e-cigarette blew up while stored in a teen's pocket, shooting itself 15 feet through the inside of a grocery store in Orange County, California.

The 19-year-old was working at an Albertsons supermarket on Monday night when the e-cigarette battery exploded after coming into contact with his keys.

The battery caused the e-cigarette to catch fire. The unit flew from the pocket, ripping his pants to the knee. The device narrowly missed a co-worker as it shot across the room, according to reports from other employees.

The teenager was taken to hospital where he was treated for burns to his thigh.

While e-cigarettes offer a safer alternative to traditional cigarettes, the trade off is a risk of explosion.
